STORY SUMMARY

HAWAIʻI VOLCANOES NATIONAL PARK - Low-level lava activity continues at the summit with the rate of inflation stalled.

(BIVN) – Precursory lava overflows continue at the summit of Kīlauea, as the volcano slowly builds to its next eruptive episode. 

Low-level activity was occurring at the vents within Halemaʻumaʻu on Wednesday morning. USGS webcams now have clear views of the summit, following several days obscured by rain and steam. 

The rate of inflation has again slowed, and has been highly variable since Tuesday morning. The tilt appears stalled compared to its previous high rate. Summit reinflation has been very unsteady since lava fountaining episode 54 on August 25. 

USGS Map: This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a USGS Hawaiian Volcano Observatory helicopter overflight on August 28, 2026, so the provided statistics are reflective of the entire eruption through episode 54 on August 25.

On Tuesday, the USGS Hawaiian Volcano Observatory said a forecast window of September 8th to 10th is likely for the start of episode 55 high lava fountaining. 

This story will be updated with the information from the USGS HVO on Wednesday, once that information is made available.
